Weldon Water Is Very Hard — Here's What It Costs You Each Year

Why Is Weldon Water So Hard?

Weldon draws its water from Codette Lake, which is part of the North Saskatchewan River system, treated and supplied by the SaskWater Codette Lake Potable Water Supply System. That makes this a surface water story, not a groundwater one, and it changes how you think about the hardness.

Surface water picks up its mineral load differently than well water. Rain and snowmelt run across the land, through soil, and into the river system before pooling in Codette Lake. Along the way, that water contacts the glacial till, clay, and sedimentary deposits that dominate this part of Saskatchewan. These deposits are rich in calcium and magnesium compounds left behind by past glaciation. The water doesn’t dissolve bedrock the way it might in limestone country; instead, it leaches minerals from the soil and sediment layers it passes over. The North Saskatchewan River drains a huge basin that includes the Rocky Mountains and the Alberta prairies, and by the time that water reaches Codette Lake near Weldon, it has had a long trip to collect dissolved solids.

The result is water measuring 10.88 GPG, or 186 ppm, which puts it squarely in the “very hard” category. That’s above the USGS threshold of 10.5 GPG for very hard water, and well above the 7 GPG mark where water is simply classified as hard. For context, the USGS puts the national average around 7.3 GPG, so Weldon is running roughly 50 percent higher than that baseline. You’re not imagining it if your glasses spot, your soap doesn’t lather the way it should, and your kettle builds up scale faster than it did wherever you moved from.

The hardness here isn’t a contamination problem. The EPA doesn’t regulate hardness as a health hazard; it’s an aesthetic issue covered under Secondary Maximum Contaminant Levels. That means the water is safe to drink, but it’s hard on your plumbing, your appliances, and your cleaning routine. The minerals themselves are the same ones you’d find in most prairie surface water, just concentrated by the geology and the river’s long journey.

How Weldon Compares to Nearby Cities

Because Weldon, and the surrounding communities served by the SaskWater Codette Lake system, all pull from the same source, the hardness picture is fairly consistent across the immediate area. If your neighbor in a nearby town serviced by the same potable water supply system complains about scale, they’re dealing with the same water you are. That’s the advantage of a regional system: one treatment plant, one source, one consistent water profile.

The comparison gets more interesting when you look further afield. Communities that draw from deeper groundwater sources in Saskatchewan often see different hardness levels, sometimes higher and sometimes lower, depending on the aquifer they tap. Some prairie aquifers produce water that makes 10.88 GPG look mild. Others, particularly those drawing from sandier formations, can be noticeably softer. But without published hardness numbers for each specific town, it’s not honest to quote exact figures. What can be said is that Weldon’s surface water supply tends to run more consistent year-round than groundwater systems, which can see hardness fluctuate with recharge and drought cycles.

The practical difference matters for anyone comparing water quality reports. A town on a different supply might show lower hardness but higher iron or manganese, since those often come from different geological sources. Weldon’s water report does list a range of detected metals including aluminum, arsenic, barium, cadmium, chromium, copper, iron, lead, and manganese, but those are all regulated under EPA health standards and are present at levels that don’t change the fundamental story: this is hard surface water from a prairie river system.

For appliance life and energy bills, that hardness level is significant. According to the Water Quality Association, hard water shortens water heater service life by roughly 30 to 50 percent, and the Battelle Memorial Institute and WQRF found about a 4 percent efficiency loss per 5 GPG in gas water heaters. At 10.88 GPG, you’re looking at meaningful scale buildup over time. The DOE notes that just a quarter inch of scale can cut water heater efficiency by up to 40 percent. That’s the real cost of Weldon’s very hard water, and it’s why the WQA estimates hard water carries a real dollar figure in energy, appliance wear, and extra cleaning products. Use the calculator on this page to see what that means for your household specifically, since the cost scales with your actual water use and this city’s specific hardness level.

How does Weldon stack up against the rest of Saskatchewan? It's very hard at 10.88 GPG — White City, Edenwold, and Emerald Park sit nearby with different numbers. See the full hardest-water ranking for context.
